According to Crypto Briefing, the Ethereum Foundation is launching an application called Universal Ethereum Signer on the Passport Prime hardware device from Foundation, running on its KeyOS operating system. The application was developed by Nicolas Bacca, co-founder of Ledger and current CEO of ZKnox, with funding from the Ethereum Foundation, and is currently in the testing phase.This application allows users to securely review and sign Ethereum transactions on isolated hardware without having to expose their private keys to their mobile phones or computers. For Passport Prime users, this is the first time the device can act as a dedicated signer for Ethereum transactions through a third-party application. Currently, users need to manually sideload the signing application onto Passport Prime. Foundation CEO Zach Herbert stated that a future application directory will allow trusted groups to push updates directly to users, expected to launch in the winter of 2026.

Tether announced that KPMG U.S. has completed an independent audit of the financial statements of TG Commodities, the issuer of Tether Gold (XAU₮), as of December 31, 2025, and issued an unqualified opinion. The audit shows that XAU₮ is fully backed by physical gold. This is the second stablecoin under Tether to complete an audit by one of the Big Four accounting firms, following Tether International, the issuer of USDT, in August of this year.During the audit, KPMG conducted a physical count and verification of each gold bar backing XAU₮, rather than relying solely on confirmations from custodians. As of December 31, 2025, TG Commodities holds 520,089.350 ounces of pure gold, valued at $2.246 billion, corresponding to the issued 520,089.300 XAU₮.The gold is stored in Swiss vaults and meets the London Good Delivery standards, with ownership belonging to the token holders, where each token corresponds to an indivisible ownership of specific gold bars. The company also hires an independent third party to conduct quarterly sampling tests of the gold bars.CEO Paolo Ardoino stated that XAU₮ is expected to become the first true competitor in the gold ETF market, as gold can be settled instantly, with lower custody costs and higher transparency. CFO Simon McWilliams mentioned that auditing the largest and most complex USDT and XAU₮ is paving the way for a comprehensive audit of the entire company.

Tron, Tether, and Chainalysis announced the establishment of a joint initiative called the "Digital Crime Task Force," aimed at identifying and combating illegal activities utilizing USDT on the Tron blockchain. The three parties stated that the task force will collaborate with law enforcement agencies through intelligence gathering to shorten the interval from threat identification to enforcement action, accelerating the asset freezing process before criminals can transfer funds. Tron founder Justin Sun stated that millions rely on USDT on Tron to sustain their livelihoods and businesses, and as digital finance reaches more people, the ability to protect must also be enhanced accordingly.The establishment of the task force comes against the backdrop of rising threats from AI-driven scams and cyberattacks in the cryptocurrency industry. Chainalysis pointed out that by 2025, the profit efficiency of AI-enabled scams will be 4.5 times that of traditional methods, with identity impersonation scams increasing by over 1400% year-on-year. Tether CEO Paolo Ardoino stated that criminals are using AI to accelerate their actions, and waiting for victims to report is no longer sufficient; Tether has collaborated with over 360 law enforcement agencies in 73 countries to freeze over $7 billion related to illegal activities.The task force plans to cover threat types including investment and romance scams, hacking attacks, terrorist financing, and North Korea-related cyberattacks. This formation follows the dissolution of a previous alliance: in 2024, Tron, Tether, and TRM Labs established the "T3 Financial Crime Group," which, according to Bloomberg earlier this month, was disbanded due to slow response and lack of coordination among members. Earlier this week, the cross-chain interoperability protocol Across resumed operations after experiencing a domain hijacking, and blockchain infrastructure provider Chainstack also disclosed that it faced an AI-driven security breach last month, leaking customer names, emails, and password hashes.

Ethereum developer Marchhill submitted the draft EIP-8437, proposing to propagate proof wrapper data through the eth/73 protocol and introducing an optional mode that allows transactions to submit raw signatures to the aggregator without pre-generating STARK proofs.This proposal supports the direct propagation of certified packages with transactions and performs independent checks of specified programs in resource-constrained sandboxes to verify witness data. The new program does not require the development of native adapters for each signature scheme separately. Additionally, the proposal plans to limit the batch queue size, clean up expired transactions, and recheck records before formally generating proofs to support failure retries.Currently, the proposal is still in the Draft stage and has not yet been merged. The developer pointed out that VM and key binding consistency verification, cryptographic verification, and performance testing are still incomplete, and benchmarking has not yet been conducted.

Ethlabs published an article on the Ethereum developer community forum, proposing to set 2027 as the target year for Ethereum to achieve post-quantum and post-AI capabilities, referring to this plan as "pqai27." The proposal argues that with the rapid enhancement of AI capabilities, the accelerated development of quantum computing, and the increased ability of AI models to discover software vulnerabilities on a large scale, Ethereum should prioritize strengthening the security of its underlying protocol to prepare for potential future cryptographic risks and cyberattacks.Ethlabs pointed out that the U.S. government has advanced its target date for addressing quantum risks from 2035 to 2030, while Google plans to achieve post-quantum capabilities by 2029. At the same time, AI is solving a large number of long-standing mathematical problems and can also discover software vulnerabilities on a large scale. Ethlabs believes that although there is currently no evidence that existing cryptographic primitives will definitely be broken by AI, the associated risks are difficult to predict accurately, making it necessary to advance security upgrades proactively.In terms of the technical roadmap, Ethlabs divides the goals into two phases: the first is "pqai-ready," which means the Ethereum consensus layer will achieve a post-quantum upgrade, allowing all users to have a path to migrate to post-quantum accounts; if existing cryptography fails prematurely, the network can still operate with reduced processing capacity. The second is "pqai-scaled," which means supporting post-quantum transactions and data availability under full network capacity, aiming for post-quantum transactions to reach the processing scale of ordinary transactions, including post-quantum signature aggregation and post-quantum data availability solutions.To achieve this goal, Ethlabs suggests reassessing the scope of the upcoming hard fork Hegotá, reconsidering upgrades that do not belong to the critical path of pqai27. Among them, Frames and related post-quantum account proposals are still regarded as key components; FOCIL needs to be reassessed for its impact on upgrade progress and post-quantum compatibility. Additionally, Ethereum needs to choose between the post-quantum transformation of the existing Gasper consensus protocol and transitioning to a decoupled consensus. Ethlabs stated that to concentrate resources on advancing pqai27, it will withdraw the Quick Slots feature previously sought for Hegotá and plans to continue promoting this feature in 2028. The Glamsterdam upgrade and its scaling plan will proceed as originally scheduled. This roadmap remains a suggestion proposed by Ethlabs and will require further discussion and determination by Ethereum core developers.

Ethereum project Golem Foundation executive Julian Zawistowski published an article reviewing the 10th anniversary of the project's launch. He stated that on November 11, 2016, the Golem project launched its token sale, raising approximately 820,000 ETH in less than 30 minutes and minting 1 billion tokens, initially named GNT, now renamed GLM.Zawistowski revealed that since 2023, the Golem Foundation has staked 100,000 ETH and distributed the staking rewards to GLM holders participating through Octant, while also supporting the construction of public goods on Ethereum. Its long-term goal is to secure this fund reserve, benefiting GLM holders and the broader Ethereum ecosystem.
